Thepresent invention relat in-window washers and wipers-and more particularly to a device which is adapted to be inserted between inner and outer windows for'washing the outer surface of the inner window when in a position intermediate the upper and lower ends of the frame. a

An object of thepresent invention is to pro-- vide an improvedwindow washer and wiper wherein the head ofthe device is pivotally mounted with respect to the handle and has first and second'f aces the first f ace providing a washing surface formed of sponge rubber and the second face providing a wiping edge integrally formed with the head andof the sa'me material.

A-further object of the present invention 'is to provide a means 7 for pos itiv'elypivotingthe win'dov's'f'washer and wiper head with respect to the handle whereby the desired face may -be engaged with the window performing the desired function.' 1 I a Another. object ofthefprese'nt invention is to provide a latch means for the means 'forpivoting the window washer and wiper head,lwhereby the head may bemaintained in either of' its pivoted positions.

A still further object of the present invention is to provide a window'wiper and washer formed a with a plurality .of nozzles in the head thereof in combination withaliquid supplyanda vacuum" through the I pressure hose for forcing the liquid nozzles.

Another object of the present invention is to provide a valve intermediatethe' ends offthe handle for controlling the flow of "fluid there through whereby the flow of fluid may be stopped when it is desired to'wash' or.wipe thewindows after spraying l and with parts section; 'j I Figure,.2 is an elevational view of;}t ehandle and Window washer, and wiper with the head in' section and in: spraying position;

Referringfmoreparticularly to the drawings, wherein. likeTffjfiumeralsi.designate like parts throughout, th nume al; I'Di designates generally a windowwasliefga" d' wiper head which is pivotallyfsecuredtothehandle l2, the numeral I4 designates generally the hoseconnecting the handle I2 with the} liquid supply means It which is cbnnecteegaua conventional vacuum cleaner and vacuum'i'pressure hose 18. The numeral 2e designates} generally the means for efiecting pi qe gg'movemenc of the head HJQwhile the numeral" 22 designates 'gen'erallythe valve means employed in conjunction with the handle l2 for controlling the flow of fluid therethrough.

'ffIhe head I 0 is comprised of a substantially tri- 'angularlyshaped elongated and hollow member 24 formed of; hard rubber or the like; Member 24 is provided with a pair of faces 25 and 28, the face 26'being forrned with alongitudinally extendingprojection 3!) providinga wiper edge 32, whilethe face 28 has secured thereto a sponge-1 rubber elongated wiping element 34 which pro videsa washinglement The wiper projection 30 and the-washer member ,34- each have their. I outer faces 36, and .38 beveled;to.vpreventt undev-i:

sirable engagement with the window during Figure 6 isa detailed partial elevational view reciprocatory movement of the window washer while spraying as in Figure 2. The head I8 is provided with a plurality of nozzles 40, 42 and 44 which extend through the face 26 and. are connected to a common conduit 46 by means of the conduits 48, and 52. The head I0 is also provided with a recessed portion 54 in which is received the upper end of the handle I2. The upper end of the handle I2 has the head I0 pivotally secured thereto at 56.

The handle I2 is comprised of a tubular rubher-like element 58 having a passage 60 therethrough and a metallic casing 62 disposed over;

a major portion of the handle. The handle is preferably of flattened form, as shownin'Fi'g'ure 4 in elliptical cross section. However, the handle may be of rectangular cross section or or circular cross section if desired. V

The handle I2 has a hose I4 secured thereto by means of the coupling conduit 54 which is engaged in the rear end of the handle I2 and the ester; end or th conduit; I 4.

The opposite end-of the Y within the cap 66 which is shown in detail in Figure; 5. The cap 66 has a downwardly extending annul ar portion '68 which is suitably engaged on'the open en d of a bottle Ill containing water orjth e like. Atube I2 concentrically formed with the cap as and extends downwardly into the bottle 19.. The upper end of the tube I2 is in comniunieation withlthe bore 14. The bore I4 is in open commur'iication with the inlet end I6 and outlet endand passage I8. The conduit I4 is secured to the outlet endand passage I8, while the vacuum cleaner hose 80 is secured to the inlet end 15., It will readily be seen that pressure from the hose of the vacuum cleaner will work as in a conventional injector and will force fluid through the conduit I4 and out the plurality of nozzles in the head I0. V

Looking nowatFigures 9, 19 and 12. it will be seen that the means 20 f0ir effecting pivoting movement of the head II] is comprised of a rigid cable or rod 84 secured to the head by means of alscrew 85 at its uper endand secured to the pin as at its lower end. The sleeve 62 isformedwith aslot 90 which is longitudinallydisposed and has a, pair or angularl'y related' slots 2 and94 connected therewith. The pin 88 isadaptedto ride withinthe slots 90, 92, 94 for vertically reciprocating thejc'able 84, the pin when engaged in either of the. slots 82 and beingadapted to retain the head pin from further pivoting movementfrom the selected position. Acoil tension spring 95 is secured to the pin BB of the detent 90 to maintain the pin 88 normally engaged within either of the slots 92hr 94 when the pin is moved to either of the ends of the slot 90.

The passage 60 through the handle I2 is controlled by means of the reciprocating valve Hill. The tubular handle 58 is formed with a first recess W2 and a second reduced cross section recess I04 in open communication with the first recess I02. The valve member 1 I30 is reciprocably disposed within the recess Hi4 and has the stem I'IIS- extending therefrom into the recess I92. The outer end of the stem I66 extends through the sleeve 62 and has a handle button I08 integrally formed therewith at its outer end. The stem I06 is also formed with a spring retaining disk I10, against which the compression spring II2 abuts when normally urging the valve out wardly. The valve I00 is of circular form and is adapted to completely close out the passage '60 when in the position shown in Figure 3. When conduit I4 is secured surface of the inner window I20.

4. it is desired to open the passage, the button I08 is depressed and the valve I00 becomes disposed within the end portion of the recess I04.

In view of the foregoing description, taken in conjunction with the drawings, it is believed that a device has been provided which will accomplish all of the objects herein above set forth. It is also believed that one skilled in the art will readily understand the operation of the window washer. and wiper-of the-present invention from aconsiderationofjthe foregoing.

As seen best in Figure 1, the inner window I20 isin raised position, while the outer window I22 is in its normally upper position. The window washer is inserted between the inner and outer windowswith the wiper head Ill facing the outer The vacuum cleaner. I8 is'actuated and the pressure hose is connected to the bottle 10- thereby providing a pressure within the hose I4. Upon depression of the valve button I08, the passage 60 is opened and liquid will pass from the bottle I0 through the conduit I4-into the handle IZ-due to the pressure of the vacuum pressure hose.

Water or other cleaning fluid will dispense: through the'plurality of nozzles in the head Ilq. Next. the head I0 is pivoted to the washing posi tion as shown in Figure 10 by means of the actuating pin 88 which is 'moved downwardly and engaged inthe slot 94. The washer is then re,-

ciprocated so that the; sponge rubber member 34 engages the surfacegof thewindow pane.

Next, the window is wiped by pivoting thehead Hl'with respect tothe handle, the pivoting being eifected by upward movement-of thevpintain the slot and thenin'to the slot 92, The projectin'gwiping edge 30 will then be in the position shown in Figure Q fOr-engagement with the window pane. Reciprocation will effect wiping of the window.
